Plagiarism free essays mean that the paper is a unique creation by a low paid writer, not a copy downloaded off a student paper sharing site.
Submitting a paper you paid someone else to write isn’t plagiarism, just fraud.
And CWS is only a tip of an ice-berg. On freelance writing sites, I regularly see available assignments to write everything from 1000 word history essays to 2000 word theory of knowledge papers to 3K papers on medical topics.
It’s not just fraud, it is cheating. I teach Object Oriented Programming and database subjects to both undergraduates and graduates. I see this frequently in technology as well. They pay others to write their assignment projects. I have found exactly, my custom written assignment projects out on these sites. Now, to get to the code you have to pay for it. Some got by cheaply with a few dollars, others paid up to $30 for one assignment. Now, not everyone is doing this but many are, mostly international students (future H1Bs) that stupid company execs are falling all over themselves to hire.
I’ve been seriously considering setting up my own site, charge them a nominal fee and then fail them and get them removed from their programs for cheating. Not much I can do about it though since it is hard to prove they cheated unless I can ID their pseudonyms at the sites and/or directly match their code to something written outside. I’ve done this in a few cases each term but I mostly catch students turning in the same code as other students.
I have so far resisted telling them that I am not failing them so much for cheating as I am for being so stupid as to blatently cheat and think I won’t catch them.
Actually, submitting a paper someone else wrote is plagiarism. Websters defines the verb to plagiarize as “to use the words or ideas of another person as if they were your own words or ideas”.
To be an effective source of fraudulent academic work, the low paid writers must not themselves engage in plagiarism (since this could result in the plagiarism being noticed). The student who turns in their product purporting it to be his or her own must be the only plagiarist involved in the process.
